Which NFPA standard governs the design of clean agent extinguishing systems?

• A. 2000
• B. 101
• C. 72
• D. 2001

Answer: (D)

NFPA 2001, Standard for Clean Agent Fire Extinguishing Systems, governs the design of clean agent extinguishing systems. This standard specifies how total-flooding clean agent systems are selected, sized, installed, tested, and maintained, including details on agent type and concentration, room geometry, discharge time, piping and nozzle layouts, detection and release sequencing, and commissioning requirements. The aim is to achieve the required agent concentration quickly to suppress the fire while minimizing risk to occupants and responders. This standard is distinct from NFPA 2000, which covers smoke management and overall life safety systems; NFPA 101, the Life Safety Code, focuses on means of egress and occupancy safety rather than system design; and NFPA 72, the Fire Alarm and Signaling Code, deals with detection and signaling rather than extinguishing design.
